The pin has an enlarged end 37 extending from the block for engagement to release the plunger, and is received within the enlarged portion 38 of the bore. A coiled spring 39 surrounds the pin and is interposed between the head 37 and the shoulder` ofthe bore for resiliently maintaining the plunger in engagement With the rack. Along the top of the bar 5 are graduations for register with the indicator finger 282 on the side of the gauge block in determining lengths of strip. c

The strip support bracket 4 is mounted adjustably with respect tothe cutter lwheel for positioning the strip in the path of the cutter teeth to effect various depths of cuts; The bracket is secured to the table by the bolts 40 which pass through the elongated slots 41 in the base portion 42k of the bracket, and which extendlongitudinally of theV table.A AOn the top `of the table isa'key 43 received within the keyway 44V in the base, of` the bracket for guiding same when beadjusted.' 'Depenqingnom the bracket and ovrthe'dge of the table'is al lug extension 45 v having a forked end received within the annular groove 46'` of the head 47, of an adjusting screw 48.' ,The screwisthreaded in the edge of the ta- 1 ble anndfa`` lock nut 49 is provided on the screw for holdingf'fthe bracket 4 in adjusted positions preparatory to tightening the bolts 40.

` Providingthe adjustable Worksupport makes possible cutting printers rules either separately i or. connected by a -very thin web of metal therebetween so as to facilitate the handling of short Diecesl l Clamping ymeans are employed for clamping the strip orV rule on the support at each side of the plane of the cutter wheel, and functioning in such a manner as toy prevent shifting of severed orV partly severed lengths during the cutting operation. Said means includes a clamp element in the form of a block slidably mounted in the Y horizontal guideway 56 in thebracket 4. The

. block 55: is` disposed and. slidable in the plane of the cutter wheel and has .two spaced-apart hooked jaw formations 57 vextending under the supportI bar-5 and projecting upwardinto cooperativeclamping relation with the bar for clamping the strip on eachfside of the plane of the cutter wheel and close thereto, so that during the cutti-iigV operation, the ends of the beveled sections are firmly held together and on the support. This I makespossible providing a beveled cut between f they areassembled into arectangular formation for printing borders about printed matter.

For positioning f the jaws in predetermined space dclamping relations Ato the strip, 'an adjusting screw shaft 58 is provided, and-is in threadvx ed. engagement with .the block'55. The screw shaft isv adjustably mounted intheL bearing 59 onthe bracket4, and `hasa hand wheel or knob v60 for operating'it.- 'A compression 4spring 61 surrounds the screw shaft and vis interposed between the end ofthe bearing'anda collar 62er; the shaft for resiliently maintainingthe jaws disengaged.k

' 76 centrally pivoted to the table at 77. `The end means includes' a nin 463l foutue top face of.

the block 55, which projects through a slot 64 'in the cover plate 65 of the bracket. Along the side of the slot are graduations 66 spaced in conformity with standard sizes of rules for register with the pin.

The clamp element is operably connected to the cutter head, so that when the head is moved downward into cooperative relation with the support for cutting the strip, the jaws are applied. The connection is eiected by a lever 70 disposed within the hollow 71 of the bracket 4 and centrally pivoted to the bracket at 72. The lever has an end 73-'extending upward, engaging the end of the adjusting screw 58. The lever 70 extends downward from its pivot through a slot 74 in the table and bent at right angles into a horizontal portion 75 which is parallel to the adjustable movement of the bracket 4. Disposed under the table is a horizontal lever 78 of the lever 476 is in contact withv the under side of the end 75 of the lever 70 through the intermediation of theadjusting Screw 79. The other endofthe lever 76 is engaged by averti-.- cally disposed plunger pin 80 passing through 100 the table. Said pin is in telescopic `connection with the stem 81 of a plunger 82 slidably mounted in the vertical guideway 83 in the bracket 13. The plunger 82 has a roller 8 4 at itsv top which engages a cam 85 A`on the lever 22. A coiled com- 105 pression spring 86 surrounds the stem of the, plunger and is interposed between the end of theA plunger and the cupped end 87 of the plunger` pin, whereby a resilient connection is effected between the plunger and thelever 76. Thus when 1,:10 the cutter head is lowered by thel operatingl arml for the cutting operation, the clamp is resiliently applied by way o-f the cam,the; plunger and `the levers 70r and 76. d u

Because of the sliding connection between; the;- levers 70 and 76, lwhen the support head-is adjusted, the clamp` is substantially maintained. in constant clamping relation to the-strip. The manner of operatingv the machine is as'.

follows. After the gauge 28,15. set for length of v rule, and the jaws are-adjusted for proper clearance with respect to the support bar 5, the-.operatorplaces the strip to heY out 'againsty the bar with one hand, holding it down on the shelf; portion 5 withfone end thereof engagingl the stop29 of the gauge block-28;Y With `his other hand the operator operates the arm 22y which. causes theclamping of the strip on the Suppert: bar and the operation of the cutterwheel infcut.-y ting the strip to length. ,'Ihusanfoperatorfisenabled .todevote the use of one-hand to the han-,- dling or adjusting of the work orstriponr thef machine, while his other handcan be controlling the cutting and clamping operationofmachlnej by the manipulation of a single control means. 135 Thisl novel control feature ofv the machiney pro-v motes precisionand-expediency in cuttingvprint-J ers rules to beve-led ended lengths both singular-1y` and in connected sections, asis Iillustrated in Figs. 8 and 9. In producing the connectedsections, 140 the operator would only havel the; gauge to adjust in addition to adjusting therstrip therewith afterl the cutting of each section. This is easilygdone` with the same hand withoutmaterially-hindering the operation of the machine. f
